2 Claims.

This invention relates to improvements in stereoscopic pictures and has for its object the provision of a device add the element of of this character which will motion or animation to the reoscopically for the purpose of holding the attention of the viewer, de-

veloping the sense of stereopsis and fusion and inducing beneficial activity of the extrinsic mus- 1 nectlon withthe cles of the eyes.

To attain, these and other ends I provide a stereoscopic picture embodying cut-out portions placed in corresponding positions in the right view and the left view thereof, a. pair of revolving discs situated immediately behind or in said cut-out portions in such part of a manner as to form a and complete said stereoscopic picture,

and a means of imparting a synchronous revolving motion to said discs in such a manner as to of that give the appearance the respective views discs.

with the invention consists in the animation to that part of are mounted upon said above and other objects in view, the

construction, combination and arrangements of parts hereinafter fully described and claimed, and illustratedin the accompanying drawing,

wherein Figure 1 is a view of the front elevationof a stereoscopic picture device constructed in accordance with my invention.

From the foregoing description, taken in conbeapparentthatlhave ac panr s drawing it should produced a device that Des Moines, Iowa 1934, Serial No. 714,92i

has many advantages Stereoscopic pictures as ordinarily used for entertainment or orthoptic treatments lack the qualities necessary to hold the observer's attention for a suitable length of time and to sufficiently stimulate the visual functions.

My invention will opsis, color and motion tion the front member with other stereoscopic this device. It will be seen that present form, depth or stereto the eye, and in addiwill be interchangeable pictures designed to fit this device will hold the attention of the observer or patient, will provide additional stimulation to the visual functions, and will induce activity of the extrinsic muscles of the eye in following the moving parts.

It should be understood that the drawing is merely illustrative and does not pretend to give exact proportions or another. Furthermore, trative of a preferred c to show exact method of holding variousmembers in conjunction with one i the said drawing is illusonstruction, it being my expectation that various changes and modifications may be made without departing from the spirit and scope of my invention.

I I claim asmy invention:- I

1. A stereoscopic picture device embodying a front member presenting a stereoscopic picture,

a circular aperture placed in the right view of said stereoscopic picture in a relative position corresponding with a similar aperture placed in the left view of said pic ture, a pair of discs fitting behind said apertures and bearing on their front surfaces designs completing and forming a part of said right and left views, a pair of gearsupon which said discs are mounted, a shaft bearing a pair of worm rear member or back gage the front member gears engaging said gears, a plate which is bent forward at either extremity in such a manner as to enand hold same in position, and said back plate designed to provide bearings for said gears and worm gear shaft, and to hold the entire mechanism in proper assembly, and an. electric motor engaging the the worm gear shaft.

end of 2. A stereoscopic-picture device embodying a front member of cardboard or similar opaque material presenting a stereoscopic picture, apertures located in corresponding positions in the right and left apertures and bearin signs completing ally spac said sears, of the worm gear to views thereof,

discs placed in said eccentrically placed desaid stereoscopic picture, latergears upon which shaft bearing worm gears engaging an electric motor engaging the end shaft, and a back plate designed provide bearings for said said discs are shaft and, gears and to hold the entire mechanism in proper assembly.
